'dsm-storybook publish' fails when path contains space

[tomnar]

Describe the bug
The dsm-storybook publish script fails when the path contains a space:

DSM =>    Creating Storybook bundle...
'C:\Users\Tom' is not recognized as an internal or external command,
operable program or batch file.
DSM =>  × Failed to build Storybook. For more details, try to run "build-storybook". For further assistance visit (https://support.invisionapp.com).

When the repository is moved to a path without space it works.

3. Make needed updates, e.g. update credentials file.
4. Run dsm-storybook publish and see it fail.
5. Rename folder to "demo".
